Evaluation of Self-Applied Tourniquets for Combat Applications, Second Phase

Abstract

In a repeated measures design, thirteen tourniquets for combat application were tested for their ease of use and ability to occlude arterial blood flow to the upper and lower extremities. To simulate field conditions, subjects completed an exercise routine and then applied a tourniquet that had been immersed in a blood analog solution and rolled in sand. Subjects applied the tourniquets while blindfolded and in seated or supine positions. Tourniquet evaluations were based on five parameters: failure rate, application time, occlusion efficacy (as determined by both Doppler and impedance plethysmography), and subjective evaluations. Results showed wide variations in tourniquet performance across the measured parameters. Inferential analysis and post-hoc group classifications allowed tourniquets to be stratified according to overall performance.
